Blisters are small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters.  Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.  

Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.

Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.

To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.

Neuropathy is the weakness, numbness, and pain in the hands and feet due to damage to the peripheral nerves. The peripheral nerves are responsible for sending information from the brain and spinal cord to the rest of your body. Causes of Neuropathy include: traumatic injuries, infections, metabolic problems, exposure to toxins, and diabetes.

Diabetes is the most common cause, with more than half of the diabetic population developing some type of neuropathy. There are several types of neuropathy and they vary based on the damage of the nerves. Mononeuropathy is classified as only one nerve being damaged. When multiple nerves are affected, it is referred as polyneuropathy. One of the types of polyneuropathy is distal symmetric polyneuropathy. It is the most common for people with diabetes and starts when the nerves furthest away from the central nervous begin to malfunction. The symptoms begin with pain and numbness in the feet and then they travel up to the legs. A rarer form of polyneuropathy is acute symmetrical peripheral neuropathy, which is a severe type that affects nerves throughout the body and is highly associated with Guillain-Barre syndrome, an autoimmune disorder that attacks the peripheral nervous system and can be fatal. Although there are many types of neuropathy, most of them share the same symptoms such as pain, extreme sensitivity to touch, lack of coordination, muscle weakness, dizziness, and digestive problems. Since neuropathy affects the nerves, those affected should be careful of burns, infection and falling, as depleted sensations disguise such ailments.

The best way to prevent neuropathy is to manage any medical conditions such as diabetes, alcoholism, or rheumatoid arthritis. Creating and managing a healthy lifestyle can also go a long way. Having a healthy diet full of fruits, vegetables, whole grains and lean protein can keep the nerves healthy. These types of food have the nutrients to prevent neuropathy. Regularly exercising can help as well, but it is best to consult with a doctor about the right amount. In addition to diet and exercise, avoiding risk factors will also prevent neuropathy. This includes repetitive motions, cramped positions, exposure to toxic chemicals, smoking and overindulging on alcohol.

Morton's Neuroma, also called Intermetatarsal Neuroma or Plantar Neuroma, is a condition that affects the nerves of the feet, usually the area between the third and fourth toe. Neuroma refers to a benign growth that can occur in different parts of the body. Morton's Neuroma strictly affects the feet. This condition causes the tissue around the nerves that lead to the toes becoming thick, causing pain in the ball of the foot.

This condition can be caused by injury, pressure or irritation. Normally no lump will be felt, but instead burning pain in the ball of the foot will be experienced. Numbness and tingling may also occur. With the onset of this condition, a person may feel pain when tight or narrow shoes are worn. As the condition worsens, the pain may persist for days, or even weeks.

Persistent foot pain should always be a concern. The foot should be examined by a podiatrist if pain persists longer than a few days with no relief from changing shoes. The earlier the foot is examined and treated, the less chance there will be for surgical treatment.

There are some factors that can play a role in the development of Morton's Neuroma. These include wearing ill-fitting shoes that cause pressure to the toes, such as high heels. Also, high impact exercise may contribute to the cause of this condition. Morton’s Neuroma may also develop if the foot sustains an injury. Another cause includes walking abnormally due to bunions or flat feet. This causes excessive pressure and irritates the tissue. At times, people are affected for no determinable reason.

Podiatrists can alleviate the effects of this condition using a treatment plan to help decrease the pain and heal the foot tissue. Depending upon the severity of the Morton's Neuroma, the treatment plan can vary. For cases that are mild to moderate, treatments may include applying padding to the arch to relieve pressure from the nerve and reduce compression while walking. Ice packs can also help reduce swelling. The podiatrist may also create a custom orthotic device to support the foot and reduce compression and pressure on the affected nerve. The doctor will probably advise against partaking in activities that cause constant pressure on the affected area. They may provide wider shoes to ease the pressure from the toes. If these treatments do not relieve the symptoms of this condition, the doctor may use injection therapy.

Surgical treatment may be recommended by the podiatrist if all other treatments fail to provide relief. Normally, the podiatric surgeon will decide on either a surgical procedure that involves removal of the affected nerve or will choose surgery to release the nerve. After examination, the surgeon will decide on the best approach to treat the problem.

Recovery varies according to the type of surgical procedure. The patient will also be instructed on the best shoe wear to prevent the return of this condition, along with changes to workout routines, if this was a cause. Preventative measures are important in ensuring the condition does not return.

Heel spurs are calcium deposits that cause bone protrusions on the heel bone. Heel spurs are usually associated with plantar fasciitis, which occurs when the plantar fasciitis in the foot becomes inflamed. Typically, heel spurs don’t cause any symptoms. However, they can produce chronic or intermittent heel pain. Those who have had the condition often describe the irritation as a stabbing pain.

There are risk factors that may make you more likely to develop heel spurs. People who have abnormal walking gaits, run and jog on hard surfaces, are obese, or wear poorly fitting shoes are more likely to develop heel spurs.

Fortunately, there are precautions you can take to avoid developing heel spurs. One of the best ways to do this is by wearing well-fitting shoes with shock-absorbent soles. Another preventative technique is to choose running shoes if you plan on running, and walking shoes if you plan on walking. Shoes are made for different activities and it is important to research a shoe before you purchase a pair.

The pain associated with heel spurs often decreases the more you walk. However, a recurrence of pain after an extended period of rest or walking is likely to occur with this condition. Those with severe heel spur pain may opt to go the surgical route for treatment.  However, more than 90% of those with the condition get better without surgical treatment. If you have a heel spur and want to know if surgery is right for you, you should go to your podiatrist and he or she will be able to conduct a pre-surgical test or exam to determine if you are an optimal candidate for surgery.
